CRYFTON .....

[abdou2014]

Is it Andy flind modified or what ?

[Geo]

No, nothing similar.
At right from attached photo is the No2 lrl and at left is the pcb from No1 lrl.

[abdou2014]

good work

[Geo]

Thank you.
The right lrl detects all metals but the left (not the same but a modified version) only noble metals.
At left (normal version) the coil is wraped on a ferrite and there is n't the black coil at front of lrl.

Hi Geo, Which is No:1 and No:2 (with Discrimination ) and Maximum Detection from how much meter for big or small object ?

[Geo]

I have locate very big objects from 300m with the No1 and from 70m with No2.

[abdou2014]

it work in VLF ?

[Geo]

One of them yes (7.1 Khz) and the other at 130Khz.

[abdou2014]

you use them alone without a transmitter ?

Ok Geo Good distance ,
Your two LRL Detect object with fast Moving from Left to Right or with very slowly Moving ?

[GOLDEN LILLY]

I guess slow sweep speed to catch the phenomenon...

Both with slow or medium motion but not quickly.

[humhum]

Ok Master , thanks . Maybe one PD is from Zahori + ...mod

[GOLDEN LILLY]

Does anybody tried the Gold Zeus PD? How is this PD compared to OBMD?

Only the battle field lazer detector work

[abdou2014]

what is the operating principle of your Battlefield laser detector , IR transmitter and HF or FM receiver or what ??

[dragomir]

My opinion that OBMD and similar devices work but not everywhere has the signal they have to capture, and this is related to the structure of the earth.

The hf receiver with the LC circuit,i dont know how this work but work :χαχαχα:

taxma, do you think that is right to post all the time irrelevant comments, in topics about specific detectors ?
Why you don't start a new thread about your cell-phone magnetometer, or your battlefield detector ?

why do not you ask the same and others who upload pictures of the subject?

hi Franco and thanjks for your response.

I was out of home for some vacation time and now i m just reading your post, that help me to continue with the project. So i apreciate your help and orientation about your free project.
When i finish a new pcb and mounting parts, i will start new test and of course i will share here my expirencies, to feedback all mambers on the forum.
Thanks and best regards

Nelson

I can not give an answer to this fact, the only thing that comes to mind is that there is not enough amplification, in fact I noticed in my lrl that (for a weak signal) it is enough to decrease the threshold slightly to lose the signal. However, if you have the compass effect this guarantees that the gain is sufficient.

Hi Geo. I just returning from my vacations.

So has i told Franco, i will restar building LRL proyects that i left for a while.
You are a very expirienced man about LRL´S, so your comments are apreciated.
For my was not easy to know at first time here on the forum, wich device was correct to build and study, because has you know many proyects and schematics where posted and also many builders has started to build units and tested normally with no success.
Indeed i goy one crypton unit from Andreas that never worked for me. But this risk was assumed by me, because it was one way to know who was the real honest man.

Today i can see more clearly that none of this devices works on all terrains or countris due to diferents field conditions. So for that, i can see now that may be some may was right and some not, depending on what they build, how they tune it up and where they tested.

I belive on Esteban devices, your devices and Franco lrl, because it shows that on the backup, was a complete interest to learn, experimenting and share information.

All and all, i will try againg my experiements, taking in mind that after all this learning years and expirences, today i have more knowing about the correct people that is keeping their work on lrs´s, without be interested on taking your money from your pocket.

Thansk Geo and will keep talking here on the forum.

Regards

Nelson

PDK don't work at my city but works at other cities, the same with Alonsos PD.
Andy Flind's MFD (or Cryfton...) don't work at my City and work a little at some places.
Franco's lrl works at my City with lower detection distance but it locates iron objects. Only one time i located copper and silver at test area. I have n't tried it at other Cities.
So what advice to give you??? Maybe to begin with the PDK if the terain at your area is good. About me i use 2 lrls with ferrite that are most better that everything else but they are very complex.
